Jessica Biel and Justin Timberlake Play House

Jessica Biel will be home alone no longer!

Although the Rules of Attraction actress/MySpace scribe had pretty much been living in sin with beau Justin Timberlake on a nightly basis, the PDA-happy couple consummated their cohabitation Friday by officially moving Jess’ belongings into the Timberhouse.

Could a JT or JB junior be the next order of business for these two?

And how long before Timberlake’s ex Cameron Diaz hears this news and has Paul Sculfor’s belongings shipped across the Atlantic in a competitive, jealous rage?
